Method and device for extracting speech features based on artificial intelligence

Embodiments of the present disclosure provide a method and a device for extracting speech features based on artificial intelligence. The method includes performing a spectrum analysis on a speech to be recognized to obtain a spectrum program of the speech to be recognized; and extracting features of the spectrum program by using a gated convolution neural network to obtain the speech features of the speech to be recognized. As the spectrum program can describe the speech to be recognized in a form of image, and the gated convolution neural network is an effective method for processing images, the speech features extracted with this method may accurately describe characteristics of the speech.
